3.3.2 Summary of User Functions in PCSTAR 2 (F2 – Configuration)
The table below provides an overview of all parameters that can be set in the configuration menu
using F2 in PCSTAR2. Reset default values are in bold type in the “Input Range” column.
Function
Input Range Description
1.0.0 Operation
1.1.0 Basic parameters
Enter 0 … 60 m or
0 … 197 ft. 1.1.1 Tank height
As per order
The tank height forms the basis for
calculating level measurements and
for the relevant current output. It is
defined as the distance between the
lower flange surface and the
reference point at the bottom of the
tank.
The output unit is determined via Fct.
1.2.4.: Length Unit
The set tank height is the upper limit
for Fct. 1.3.4: Scale I1 max (if Fct.
1.3.1 is set to “Level” or “Distance”).
Note: the device will not measure
beyond the programmed probe length
if the current output is configured to
measure distance or level .
1.1.2 Dead zone
Enter a value
Fct.1.5.1(Detection
delay) … probe
length.
Warning : Critical Parameter • Twin probe with
probe length<1m
or 3.3 ft
0.2 m or 8 in
• Single probe or
twin probe with
probe
length >1m
or 3.3 ft
0.4 m or 16 in
• Coaxial probe
0 m or 0 in
The dead zone is the minimum
measuring distance from the process
connection (reference point) to the
surface of the product. So as not to
impair measurement accuracy, the
minimum values given in Section
5.2.3 should be adhered to.
The BM 102 will ignore signals in the
dead zone and display the last
reading taken.
The output unit is set via Fct. 1.2.4:
Length Unit
1 … 100 seconds 1.1.3 Time constant
5 seconds
This function filters possible signal
fluctuations when the liquid is
turbulent.
